With streaming I get to see quite a few shows and some of the scoring is head scratching when I view score tally sheets.
e.g.
1. Red is running around the ring & rarely throws punches, yet the score is 10/9, which IMO should be 10/8
2. Blue is ahead 10/9, but if knocked down, score is automatically 8/10 ??
I think the pluses for open scoring outweigh the negatives. At least if a fighter is going to get stiffed it gives him an early warning and he can go hell for leather for the KO.
